xml_to_schema: A lot in this commit

A. Both the parallel and singular implementations are working.
  i. The parallel one takes ~3m to run through the entire ClinVarSet, including breaking it up into smaller files, and produce a final JSON representation.
  ii. The singular one takes ~5m
B. Testing the counts is also good to go with the test_counts function, which looks at the source xml and the output json and compares their object count totals.
